The water-oil separating pipe
Technical field
The utility model relates to a kind of separator, particularly relates to a kind of separator for water-oil separating.
Background technology
In oil well production and engineering, usually need with crude oil and moisture from, at present, oil-water separation method has following several: gravitational separation process, isolated by filtration method, dissolved air flotation method, adsorption method of separation etc.These separation methods, some complex structures, the cost that has is expensive, production efficiency that have is not high, and impact is normal produces and work, causes the waste of crude oil and the pollution of environment.How to accomplish that cost is low, separative efficiency is high, and energy savings, be instantly to need one of technical barrier that solves again.
The utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, cost is low, effectively realize the separator of water-oil separating.
The utility model water-oil separating pipe, comprise spiral centrifuge tube, the radius of gyration of described centrifuge tube reduces from top to bottom successively, described centrifuge tube end tube chamber is provided with demarcation strip, described demarcation strip is perpendicular to the described centrifuge tube helicoid at its place, place, described demarcation strip is separated into inboard oil-out and the delivery port in the outside with described centrifuge tube end tube chamber, and described oil-out is communicated with flowline, and described delivery port is communicated with described outlet pipe.
With prior art first than, the utility model has utilized centrifugal force, oil, water mixed liquid are accelerated in the spirality centrifuge tube from top to bottom gradually, and the crude oil that proportion is little arrives inboard, enters flowline from oil-out, heavy water is thrown to outer survey and enters outlet pipe from delivery port, realize oil, moisture from, if once can not separate fully, can repeatedly recycle, until separate thoroughly, simple in structure, cost is low.
The utility model water-oil separating pipe, wherein said centrifuge tube caliber 40-60mm, high 300-1000mm.Adopt realization oil, moisture that this size helps maximum efficiency from.
The utility model water-oil separating pipe, the cross section ratio of wherein said delivery port and oil-out is 0.8-1.2, adopt realization oil, moisture that this size helps maximum efficiency from, adjust the cross section ratio of the mouth of a river and oil-out according to the proportion in oil, water mixed liquid, the oil-out cross section more greatly when the many water of oil are few, when the few water of oil was many, the delivery port cross section more greatly.
The utility model water-oil separating pipe, wherein said centrifuge tube tapering are 10 °-45 °, when oil, adopt when aqueous mixtures belongs to fine particle stage material than Small Taper, adopt larger tapering when belonging to the coarse fraction material.
Below in conjunction with accompanying drawing, the utility model water-oil separating pipe is described further.

The specific embodiment
As shown in Figures 1 and 2, the utility model water-oil separating pipe comprises spiral centrifuge tube 1, centrifuge tube 1 caliber 60mm, high 1000mm, the radius of gyration of centrifuge tube 1 reduces from top to bottom successively, centrifuge tube 1 spiral tapering is 30 °, centrifuge tube 1 end tube chamber is provided with demarcation strip 2, demarcation strip 2 is perpendicular to centrifuge tube 1 helicoid at its place, place, demarcation strip 2 is separated into inboard oil-out 11 and the delivery port 12 in the outside with centrifuge tube 1 end tube chamber, delivery port 12 is 1:1 with the cross section ratio of oil-out 11, and oil-out 11 is communicated with flowline 3, and delivery port 12 is communicated with outlet pipe 4.
The utility model in use, oil, water mixed liquid are from top injection centrifuge tube 1, the radius of gyration of centrifuge tube 1 reduces from top to bottom successively, make mixed liquor flow velocity therein increasing, the oil that proportion is less is stayed the inboard gradually, the water that proportion is larger is being thrown to the outside, under the effect of centrifuge tube 1 end tube chamber demarcation strip 2, oil enters flowline 3 from oil-out 11, water enters outlet pipe 4 from delivery port 12, realize water-oil separating, if once thoroughly separating oil and water also can repeatedly repeat aforesaid operations.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
